Definitions

  • the invention relates to a sprung suspension of a rigid axle on the chassis frame a vehicle, in particular lorry or bus, with features of the Preamble of claim 1 specified type.
  • the invention is based on a sprung rigid axle suspension, as in commercial vehicles the Applicant came with the generic features for use and from Fig. 9 can be seen. It is a drawn axis.
  • This axle suspension comes at a fraction of the leaf spring in the area of the rear attachment becoming effective spring catch device for use, from a stop at the front attachment member of the leaf spring forming rocker and a frame-fixed Stop surface exists.
  • the leaf spring stored in the opposite direction, that is, the Swingarm is given at the front end.
  • the stop on the rocker is primarily used for jounce path limitation of the frame with respect to the axis and secondarily for catching the leaf spring when it breaks at its rear bearing point.
  • the spring catch device according to the invention is immediately effective when the leaf spring breaks its front attachment point.
  • the leaf spring shifts in this case rear. This movement is stopped but already after a short way, because in this Longitudinal displacement to the rear deflected rocker after a short angular movement comes with her stop on the top of the leaf spring to the plant and then their other Displacement blocked to the rear. It is then the axle of the rigid axle though something wrong, that is, no longer perpendicular to the vehicle's longitudinal axis. This disadvantage but can be compensated at slower driving on the wheel steering.
  • the safety gear according to the invention hinders the deflection of the chassis frame to the axis not because the arranged on the rocker Stop in each jounce state of the frame with respect to the axle of the Starrachse a more or less large distance from the leaf spring top spaced remains.
  • FIG. 9 There is a vehicle, z.
  • a Section of a part of the chassis forming the frame side member 1 shown on the a live axle with its axle body 2 is sprung hinged and fixed.
  • About the upper bearing 10 on the rocker 7 is the connection made to the bearing block 9.
  • a shock absorber 11 As other parts of the rigid suspension are too call a shock absorber 11, the top of a frame-fixed bracket 12 and below on Axle body 2 is articulated, and a U-shaped stabilizer 13, with its transverse leg hinged on the axle body 2 and with its two U-legs to a respective holding bar 14 is suspended with its upper end to a frame-fixed block 15.
  • a stop buffer referred to With 16 is a stop buffer referred to, which is mounted on top of the leaf spring 3 and in cooperation with a frame-fixed stop surface 17 the Einfederungsweg of the frame. 1 limited with respect to the axle body 2.
  • a device after a breakage of the leaf spring 3 could be effective in the region of their front spring eye 4, is in this known Axle suspension was not provided.
  • the invention provides appropriate remedy, as described below.
  • a spring catching device provided, which, when the leaf spring 3 in its front mounting area 4 breaks, becomes effective.
  • This spring catching device consists of a relation to the aforementioned known modified, specially designed rocker 7 'and an this (seen in the direction of front leaf spring mounting point 4) spaced from the lower bearing 8 arranged stop 18th
  • This stop comes 18 - regardless of his case by case different training and arrangement on the rocker 7 '- after a front breakage of the leaf spring 3 and a Shifting the same backwards due to the associated pivoting the rocker 7 'at the top 19 of the leaf spring 3 to the plant, whereby the other Shift to the rear is blocked - see Fig. 2, there the dashed line. at intact leaf spring 3, however, the stopper 18 remains in each jounce state of the Frame 1 with respect to the axle body 2 of the rigid axle a more or less large Distance from the leaf spring top 19 spaced - see Fig. 2, where the representation with solid lines.
  • the rocker 7 ' consists of two from each other spaced plates 20, 21 with mutually aligned upper holes 22, 23 and spaced therefrom aligned lower bores 24, 25.
  • one of two plates 20, 21 on the inner bearing surface 26 of the bearing block 9 and the other of the two plates 20, 21 on the outer bearing surface 27 of the bearing block 9 fitting over one the upper holes 22, 23 and a transverse bore 28 in the bearing block 9 penetrating Bearing screw 29 mounted on the bearing block 9 swinging.
  • the lower holes 24, 25 serve in the region of the lower bearing 8 for the passage of a bearing screw 8 'for the attachment of the rear spring eye 6 of the leaf spring.
  • Both plates 20, 21 are preferably made of steel or other sheet metal by punching and bending.
  • the rocker 7 by a seen from above U-shaped, preferably made of steel or other sheet metal stamped and bent part educated.
  • One of them is a side wall with 32, the other one, the first (32) parallel side cheek with 33 and one whose both side cheeks 32, 33 in front with each other connecting crosspiece designated 34.
  • the side cheeks 32, 33 are the same as in the Plates 20, 21 of the first embodiment aligned upper holes 22, 23 and spaced therefrom lower holes 24, 25 given.
  • the rocker 7 'of FIG. 6 to 8 comes in mounting position with their side walls 32, 33 at the contact surfaces 26, 27 of the bearing block 9 to the plant and is the same as in the first Embodiment over an upper holes 22, 23 and the transverse bore 28th in the bearing block 9 penetrating bearing screw 29 mounted on the bearing block 9 swinging.
  • the holes 24, 25 are also used here as in the case of Fig. 1 to 5 for implementation a bearing screw 8 'for attachment of the rear spring eye 6 of the leaf spring.
  • the transverse web 34 of the rocker 7 'according to FIGS. 6 to 8 has a Lower edge, which forms the stop 18 and preferably to the top 19 of the Leaf spring 3 extends in parallel.
